Review of my consultation at a Gangnam vision correction clinic

I recently visited a few vision correction clinics in Gangnam for consultations, and I could definitely tell the systems and equipment were different. They conducted the examinations very thoroughly and provided detailed explanations, so I felt confident. However, since there are so many clinics in Gangnam, I'm having trouble deciding where to choose. It feels even more confusing because the surgeries recommended by each hospital vary slightly. If anyone has actually undergone surgery at one of these Gangnam clinics and has any reviews, please share them.
